# Customize connector handler class

In Connectivity Studio, usually, you can design the integration setup by configuration. Sometimes, it can be required to use a customization. This topic explains the standard connector handler classes in Connectivity Studio and how to customize these classes. Only use customized classes if you really need specific functionality.

### **Standard connector handler classes**

For connectors, several standard handler classes are available. Each connector type has its own handler class:

| Connector type | Handler class | Description |
| --- | --- | --- |
| D365 F&SCM | BisConnectorAxDatabase | This handler class exports data from or directly imports data into D365 F&SCM tables. |
| Database | BisConnectorODBC | This handler class exports data to or imports data from an external database via ODBC or an external Azure SQL database. |
| Staging journal | BisConnectorStagingJournal | This handler class exports data from or imports data into a staging journal. |
| Azure file storage | BisConnectorWindowsFolder | This handler class exports data to or imports data from a file. |
| Web service | BisConnectorStreamWebservice | This handler class imports data from a stream or exports data to a stream. |
| Blob Storage | BisConnectorStreamBlobStorage | This handler class exports data to or imports data from a file in a Blob container. |
| Upload and download | BisConnectorStreamManual | This handler class imports data from an uploaded file or exports data to a file and downloads it. |

### **Customize connector handler classes**

You can use a customized connector handler class. To do so, extend a standard connector handler class. For each customized connector handler class, you can change these methods as desired:

| Method | Description |
| --- | --- |
| getNextInstance | Returns the data sets. So, for the connector type Azure file storage, it returns the next file. |
| preAction | The actions if the connector is used as source connector. |
| postAction | The actions if the connector is used as target connector. |
| close | Closes the connector. |
